The decision to end TPS for Nicaraguans is part of President Donald Trump's broader efforts to tighten restrictions on immigration. Hundreds of thousands of undocumented immigrants from across Central America live and work in the United States, but some are protected from the threat of deportation under the TPS program.

Thousands from both Nicaragua and Honduras were given the special status in 1999 after Hurricane Mitch devastated Central America. In all, TPS protects more than 300,000 people from nine countries living in the United States.

Trump's administration was faced with a Monday deadline to announce its decision on Nicaragua and Honduras.

Critics have complained the TPS program allows participants to repeatedly extend their stays in 6-month to 18-month increments in case of a natural disaster, civil strife, or other emergencies in their homelands.

In the case of Nicaragua, acting Homeland Security Secretary Elaine Duke decided the conditions caused by Hurricane Mitch "no longer exist, and thus, under the applicable statute, the current TPS designation must be terminated," the Department of Homeland Security (DHS) said in a statement.

The TPS for thousands of Nicaraguans was due to expire on Jan. 5, 2018, but it was delayed by 12 months "to allow for an orderly transition."

"This will provide time for individuals with TPS to seek an alternative lawful immigration status in the United States, if eligible, or, if necessary, arrange for their departure," the DHS statement said.

For Honduras, Duke concluded that the DHS needed more time and information to make a determination, so the current TPS designation was extended for six months to July 5, 2018.

Supporters of TPS slammed the administration's decisions.

UNITE HERE, a labor union representing hospitality industry workers, condemned what it said was an "inhumane and immoral decision that will have devastating impacts on hundreds of thousands of families, and the American economy."

Asked whether the Nicaraguan TSP recipients would be subject to deportation once their protection runs out, one administration official said: "We prioritize criminal aliens and those who have a final order of removal. Your typical TPS recipient will not fall into those priorities."

"However we stand by our position that all persons who are here illegally are eligible for removal, but they will not be targeted for removal," he added.

The officials said the administration would support any effort by the U.S. Congress to find a more permanent solution for the Nicaraguans.

The other countries with TPS designations are El Salvador, Haiti, Nepal, Somalia, South Sudan, Syria, and Yemen. A decision on Haiti and El Salvador is due later this month.

The program was enacted by Congress in 1990 to protect immigrants fleeing war or natural disasters.
